That’s the fun thing about viruses. They mutate. I also got omicron despite having 3 vaccines at the time. 2 Moderna plus a booster. The current round that’s out, number 4 for those that got them as they rolled out, was specifically made for omicron and it’s derivatives. I got that this fall after I got sick at the end of spring and have been exposed multiple times since with no infection. It’s like wearing a long sleeve shirt in September. It’ll keep you warm enough, but when December comes that protection isn’t enough and you need something stronger. The virus mutates and experts can’t really predict how the major mutations will occur. They try to react as fast as possible, which is why the newest vaccines are so effective against omicron derived variants despite the first doses released being pretty useless to them.

So, you were thrice vaccinated, got omicron, and were then exposed to a new variant + 4th boost, with no ill effect. Given that the initial 3 vaccinations did not protect you, is your assumption still that the 4th dose was the ultimate protection in your exposures vs natural immunity? I’m reading your comment as: was vaccinated, got sick, then didn’t get sick after subsequent exposure.

Thrice vaccinated, those three were based on the first variants. Omicron gains traction. Get omicron. Four months later get vaccine made for omicron. Four months since many exposures, no infection, over 8 months after omicron infection.

Ah, so the assumption is that natural immunity’s effective period is equal to that of vaccination.
